And what areas does a Market Area include?
A Market Area is a geographical area where Nielsen measures media consumption, ranked by local television homes. A market area not only includes the urban center and suburbs, but it also includes the surrounding counties (aka trade area) where small towns and rural homes receive the same television signals. There are 210 market areas in the United States. New York City is the largest Market Area, and Glendive, MT is the smallest Market Area.
